The 6281 valve is a servo-assisted solenoid valve of the S.EV series. A minimum differential pressure is always required for the function of the valve. Various diaphragm material combinations and methods of operation are available depending on the application. The standard brass housing satisfies all European drinking water requirements. Dezincification-resistant brass is available for other markets. The housing offering is rounded out by a stainless steel version. To reduce power consumption in operation, coils with "Kick and Drop" (KD) electronics assembly (double coil technology) are available. The valve can be equipped with manual override for easy maintenance and commissioning. NEMA 4X is available on request.

Servo-assisted diaphragm with diameter of up to DN50
Vibration-proof, central screwed coil system
Damped design for quiet closing
Energy-saving double coil technology with kick and drop variant
Explosion-proof versions
